    Release Information

    Statement introduced in Junos OS Release 17.4.


    Enables inline mode of performance monitoring. For Ethernet interfaces on Modular Port Concentrators (MPCs) in MX Series routers only, delegates the processing of the protocol data units (PDUs) to the forwarding ASIC (that is, to the hardware). On MX Series routers, you can configure inline mode of performance monitoring only if the network services mode on the router is configured to enhanced-ip and enhanced connectivity fault management mode (enhanced-cfm-mode) is configured. By enabling inline mode of performance monitoring, the load on the CPU of the line-card is reduced and you can configure an increased number of performance monitoring sessions and achieve maximum scaling for service OAM performance monitoring sessions.

    Note: MPC3E (MX-MPC3E-3D) and MPC4E (MPC4E-3D-32XGE-SFPP and MPC4E-3D-2CGE-8XGE) do not support inline performance monitoring. User-defined Data TLV is not supported if you have configured inline mode of performance monitoring. Also, only 12 history records per PM sessions are supported.


    Inline mode of performance monitoring is disabled by default.
